How much baseboard do I need for a 12×14 room?
A 12 × 14 ft room has 52 feet of wall. Minus 2 doorways that is 46 linear feet of baseboard, or 4 boards of 16 ft with 10 percent waste (5 boards of 12 ft). Shoe molding takes the same 46 feet. Adding crown molding takes 52 feet (4 boards), and casing the doors and two windows takes 98 feet (8 boards).

Full trim list for a 12×14 room
- Baseboard: 46 ft, 4 boards of 16 ft. Use 3-1/4 in for 8 ft ceilings, 5-1/4 in for 9 ft.
- Shoe or quarter round: 46 ft, 4 boards of 16 ft, for hard floors only.
- Crown: 52 ft, 4 boards, if you want it. Buy 15 percent extra; compound miters eat material.
- Casing: 98 ft for 2 doors both sides plus two windows, 8 boards.
- Supplies: 1 box of 2 in finish nails (or 18 gauge brads for a nailer), 2 tubes of paintable caulk, wood filler, and a quart of trim paint per 100 to 150 ft. The paint calculator for this room covers the walls.
What trim for a 12×14 room costs
Baseboard alone: $64 to $128 in primed MDF at $1 to $2 per foot, $128 to $224 in primed pine, or $256 to $512 in stain-grade oak. The whole package of baseboard, shoe, crown, and casing is 242 linear feet, roughly $363 to $968 in paint-grade material. A finish carpenter charges about $5 to $10 per linear foot installed for baseboard and $8 to $15 for crown, so $230 to $460 for the baseboard in this room. Installing it yourself takes an afternoon with a miter saw and a brad nailer; cope the inside corners rather than mitering them and they will stay tight when the house moves.
Common questions
How many linear feet of baseboard for a 12x14 room?
46 linear feet after subtracting 2 standard 3 ft doorways from the 52 ft perimeter. Buy 51 feet to allow 10 percent for cuts.
How many boards of baseboard for a 12x14 room?
4 boards of 16 ft, 5 of 12 ft, or 7 of 8 ft. Longer boards mean fewer joints; plan each wall so any joint lands on a stud and use a scarf joint, not a butt joint.
How much crown molding for a 12x14 room?
52 linear feet around the full perimeter, which is 4 boards of 16 ft with 15 percent waste for the compound miters. Crown is not reduced for doorways because it runs above them.
